thats good but why does this

twizy It looks like a bec project

I saw that in one of the mags last week - two jet turbines charging the batteries!!

That is a cross between a BMW C1 and a smart car - ended up with the worst of both!

Got to give the smart design it dues.
Its ended up being the base design for all city cars.

Smart doesnt make much sense in the uk however go to paris of roma and you see how good they really fit in with the city settings

I know a chap who works for Bladon Jets - the people behind the Jag jets and have even handled a compressor wheel. Amazing!

So, nah nah nah nah nah

sounds a bit fishy to me.

28g/km and only 560miles to a tank.

Polo Blue motion gets 80mpg, and generates 91g/km.

So, either this 780bhp jag does about 300mpg, or it runs on a low carbon fuel (hydrogen generates no carbon, but something like methane has relatively low carbon output).


Actually, the other numbers. 100mph to 200mph in 2.1seconds would require the thing to weigh 380kg (assuming there are no losses and no wind-resistance).


Sounds like the journalist went to the Clarkson school of engineering, or the Jaguar marketing department have got a calculator for Christmas.


Don't forget the original jaguar/rover gas turbine powered car.

Jaguar always have been a bit optimistic in their figures

That said, jet engines are supposed to be over 90% efficient wheras petrol engines are around 33% and TD's around 37% so you never know

Certainly the fastest battery charger on the road anyway


JoelP - 9/10/10 at 07:05 PM

Nothing totally impossible there - saying the range is 560 means nothing, because it doesnt say if that is just off the batteries (which it cannot be) or from a 5000 litre tank of jet fuel (which would then be very poor MPG).

The 2.1 seconds referred to the 62-100mph time, which is easily doable with 780bhp.

What bothers me is how the turbines will be harnessed to the chargers, and how overall efficiency would be affected by there being so many stages between stored chemical energy and kinetic energy in the car itself.

Iv just watched this which i think answers some of our questions and has made me want it even more!!!


Mark Allanson - 9/10/10 at 11:24 PM

Julian Thompson was also the leading light in the Elise design and prototype.

Trains went diesel/electric many years ago, there must be some advantages?
